Attackers can submit a crafted POST request to inject an attacker-controlled serviceUrl that is persisted and used for all subsequent bot replies, causing the server to send live Microsoft OAuth access tokens in Authorization headers to the attacker's host and enabling blind internal network access.","state":0,"publishedAt":"2026-09-26T13:23:43.143+00:00","modifiedAt":"2026-10-08T15:21:54.188+00:00","affected":[{"ecosystem":"Vendor product","name":"server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"budibase\",\n                    \"product\": \"server\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/%40budibase/server\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"3.45.0\"\n                        },\n                        {\n                            \"version\": \"3.45.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":6.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/Budibase/budibase/security/advisories/GHSA-942w-fccr-8r3c","https://www.vulncheck.com/advisories/budibase-before-3.45.0-ssrf-and-oauth-token-exfiltration-via-teams-webhook"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100681","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100681","identifiers":["CVE-2026-100681"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
